Title: Eddy current coupling
Inventor: SAKUMA KIYOSHI
IPC: H02K49/02
Filed: 1978-10-13
Abstract: PURPOSE: To improve efficiency of a motor by forming a layer of material with higher electric conductivity than the material of an eddy current on the surface  facing the magenetic pole of the eddy current composed of a magnetic substance.  
     CONSTITUTION: When power is given to a motor 2, an eddy current cylinder 5 rotates. When direct current is applied to a coil 13 in this state a click 6a is maggetized into an N pole and a click 6b is magnetized into an S pole. Therefore, the magnetic flux starts from the click 6a, crosses a layer 7 of high electric conductivity, pierces an eddy current cylinder and reaches the click 6a again through the layer 7, the cick 6b, a york 11. Therefore, eddy current produces on the eddy current cylinder 5 and the layer 7 and crossed magnetic poles 6 rotate. The rotation of the crossed magnetic poles 6 is transmitted to an output shaft 9. At this time, the layer 7 is of small resistance, eddy current runs well and efficiency is improved. Speed control at a wride range can be carried out by regulating the current flowing through a coil 13.

Title: Connection control system in radiotelephone system
Inventor: TOYAMA HIDEKI
IPC: H04W84/10
Filed: 1988-05-23
Abstract: PURPOSE:To eliminate that a radiotelephone set receives an unnecessary call by controlling the receiving of a signal after a code to indicate a group included in any incoming call signal sent from a connecting device when the radiotelephone set controls its connection. CONSTITUTION:When the incoming call signal from a wired telephone line 2 is sent to a radio line 4, for each of radiotelephone sets 5a..., an electric field detecting circuit 26 detects the signal with intermittent reception. A receiver 21 extends a receiving state and reads a group code included in the incoming call signal. Time twice as long as incoming call signal time is enough for extended time at that time, and since the group code is common among the telephone sets 5a..., the receiver 21 can read information related to the group code included in any incoming call signal. When the read group code coincides with another group code set by the receiver 21 itself, the receiver 21 further extends receiving time and receives all kinds of incoming call signals from a connecting device 3. On the other hand, when the read group code does not coincide with the group code set by the receiver 21, the receiver 21 judges that the incoming call is not the one for the receiver 21 itself and does not extend the receiving time since it is unnecessary to read a individual code included in the incoming call.

Title: Automatic recalling system for non-answer of called subscriber
Inventor: IWAI KIYOSHI
IPC: H04M3/424
Filed: 1977-10-19
Abstract: PURPOSE:To ensure the automatic recalling service for the calling subscriber when no answer is given from the called subscriber, by installing the automatic transmitter. CONSTITUTION:Subscriber A's call of PB telephone is detected through sutomatic transmitter COE, and subscriber A is connected to PBOR by the relay action within LLF. With reception of the called subscriber number, MKR operates to select IOT or OGT. Thus, a channel is completed, and at the same time the start information is sent to COE. The COE releases the channel to IOT or OGT in case no answer signal is given from the called subscriber in a fixed time after the start. Thus, a connection is given to automatic transmission register sender CORS, and a special tone is sent to subscriber A. Then subscriber A transmits the called number again to have on-hooking. As a result, CORS gives calling with every fixed time, and COE completes the channel to subscriber A when the called subscriber gives an answer.

IPC: G03G15/08
Filed: 1990-05-15
Abstract: PURPOSE:To surely prevent the occurrence of a history image by using a developer having the same polarity as that of an image carrier, carrying out reversal development, and simultaneously, elastically rubbing a rubbing member on the image carrier. CONSTITUTION:Toner T is sent from the developing roller of a developing/ cleaning device to form a toner image. At this time, the toner T sticks to a region irradiated with light, and the reversal development is carried out. The toner is electrified to negative, and a negative voltage is applied on the developing roller. Then, residual toner images or positive and negative electrostatic latent images are left on the surface of a photosensitive drum 1 after a transfer is performed. In these toner images or electrostatic latent images, first, negative latent images are erased by a distaticizing lamp, and then, they are carried to a stirring unit 7, stirred, and nonpatternized. In the stirring unit 7, the residual toner images and electrostatic latent images are finely disturbed till a reading unabled state is obtained while bringing a brush-like printing body 21 into contact with the electrostatic latent images and imparting mechanical and electrostatic force. Thus, the surface of the photosensitive body 1 has no longer information as a character or an image.
